My new one: My hero attacks a rainbow starship in low orbit by jumping onto the deck and heading for the enemy bridge and needed to go through the window to get at the pilot, I got lazy and decided to do the procedure as a feat... It failed causing him to crack his nose open and fall into megalodon infested waters, I have pictures somewhere.

My hero attempts to jump onto a flying aircraft, this caused a confusion of jumping onto a moveing target, 1 "what i says gose roll later" and yay he lands on the wing... only to be swiftly pulled into the jet engine of a nearby enemy fighter (atleast the damage roll was good).

mine isn't most painful its most pathetic. nuclear warhead falls out of the sky and crushes my heros leg. after a turn of hacking at his leg, he crawls away, falls into a ditch and gets eaten by squirell due to a What i Say Goes roll.

When life gives you lemons, make grape juice then sit back and let the world wonder how the f*ck you just did that.

Well since this thread has seemingly been reanimated i might aswell share a death:
Ahem (clears throat) once upon a time in a rebel base an AN MPT used its jumpack ability and landed on the enemy hero the herosurvived and used a stupendos feat to throw the MPT away and....FAILED miserably the MPT went up with his throw but then went down on the hero again and squished him into a red paste

Read my signature, and if you don't laugh I'll be incredibly surprised.

Best Death of all time:
Religious Fanatic Hero Malchiel (with 2 heroic feats per turn, 4 d10s of armor, and 5 d6s of damage) goes over to my brother's hero, rips out his intestines, and strangles him with them

You're disappointed with death by strangulation, by intestines? Preposterous!
Well, later on that game he used a heroic feat to "Call Down The Wrath of God Upon His Foes" by hitting them all with a lightning bolt. Let's just say that the metal cross on his back didn't quite agree with that lighting bolt, and he ended up the equivalent of deep fried Kentucky Fried Chicken. I'll post pics of him in the army section. Actually a pretty easy build, to make him and his soldiers that is.

Minutes ago I had a battle with Pockyfreak. On the first turn her hero summoned a giant panda that fell from the sky, killing nine of my thirteen-strong army. Then her army (which consisted almost entirely of mages) summoned five bigger fishes onto one of the remaining troops, killing it. Luckily two of the attempts failed and two fishes fell on top of the mages, killing five.

Then I called in a nuke. It missed.

Pockyfreak summoned four more bigger fishes. Only one was successful. It fell on my OTC warrior but he chainsawed it apart. The other three fishes killed one mage each.

Pockyfreak's hero reached the giant Bionik sword we were fighting over. My OTC warrior charged her and she parried his attack with the Bionik sword. The OTC easily ground the sword to dust.

With the objective gone, we had no reason to fight each other anymore. Our armies allied to mutilate a peach corpse found among the dead.

A particulary Stupid death was, my Viking champion had slaid hundreds of Enemies in a post apoc style RPG, Only to at the end, Get shot by his teammates for accidently eating a Mnip (a Mnip being a bastardic, but pathetic, alien which bends reality when enough of them gather, they can also wipe out a planets atmosphere in about a week, they breed like super rabbits on viagra)

Well... most painful death would have to be the time i had a minifig throw a spear at a fighter jet. It missed and hit the Leviathan class starship behind it. The spear lodged itself in a vertical stability disk, causing the ship to crash... Onto the minifig. If that wasn't bad enough the 6 fusion cores in the back simultaneously erupted, causing the planet to implode.
